How is polymerisation carried out?
There are 2 types:- Addition polymerisation is polymerisation in which monomers are joined across the double bond, for example polyethene. Condensation polymerisation is when water is lost from the two monomers for example the polymerisation of nylon, the two monomers are a diamine and dicarboxylic acid. From the amine an H goes and combines with and OH from the acid to form water. From this reaction, 2 moles of water are lostto form nylon -NH-[ ]-NH-C=O-[ ]-C=O-
What is polymerization versus catalyst?
In polymerisation a number of monomer (basic entity of polymer) get together to form a polymer.For example carbon tetra chloride joins other molecule of latter to form teflon. Catalyst catalyse(help in completion) polymerisation reaction.
What happens in the process called addition polymerisation?
a chemical reaction in which simple molecules are added to each other to form long chain molecules without by products
What is the name of the reaction when 2 monomers are split?
polymerisation. 2 monomers split to forn a polymer
What is polymer?
nothing
What are the examples of polymerisation?
polyethylene,polyvinylchloride
What technology is used in the manufacturing of polythene?
Polymerisation
What is electropolymerization?
polymerisation in the presence of an electrical current
What is condensation polymerisation?
Condensation polymerisation is when two molecules of the same substance (monomer) react together to form polymer chain (like polythene) and eliminate a smaller (usually water) molecule. For example, Nylon-6 is prepared by using condensation polymerisation of ε-Caprolactum
When monomers join up the process is called?
polymerisation.
What process joins two monomers?
Addition polymerisation
What is the heat of reaction of ethylene when form polyethylene?
3350 - 4185 J/g for polymerisation of ethylene gas taken from eng-tips.com ref Plastics Materials 5th ed J A Brydson 1989 p198
